CARBlNE-H'OOK- SPECIFICATION forming part of Letters Patent No. 781,171,dated January 31, 1905. Application filed March 28, 1903. Serial No.150,022.

To all whom it may concern:

Be it known that I, SAMUEL ADLER, a subject of the Emperor ofAustria-Hungary, residing at Vienna, in the Province of Lower Austria,in the Empire of Austria-Hungary, have invented certain new and usefulImprovements in Carbine-Hooks or Hooks Having a Spring or PivotedClosing-Piece; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and

' to letters of reference marked thereon, which form a part of thisspecification.

This invention relates to the combination, with carbine-hooks r hooks,having a tongue, of a locking device which is so arranged as to hold thespring or pivoted closing-piece thereof open when it is pressedinwardly, so that the fingers of both hands are completely free foreffecting the hooking and securing while the closing and opening of theclosing-piece of the hook can be effected by thepressure of a finger,whether such piece be under spring action or not. The locking memberconsists, mainly, of a bar applied either to the tongue or to the hook,which on being pressed inwardly is either forced sidewise or is pressedthrough an opening in the closing part or in the hook-stem and at thesame time is made to engage the latter by means of a projection ornotch, whereby the closing-piece is held in the open position and canonly return to the closed position if pressure is exerted upon the saidprojection in the contrary direction.

In the accompanying drawings, in which like parts are similarlydesignated, are shown various forms of the above-described lockingdevice for hooks as applied to double-headed links, the heads or studsof which are locked together by the carbine-hook.

Figures 1 and l show a hook made of a single piece of spring metal, themeans to hold the hook open formed on the end of the tongue. Figs. 2 and2 are sections showing the locking member in front elevation. Figs. 3and 4 show the hook in locked open position. Figs. 5 and 5 show amodification, and Figs. 6 and 6 sections showing the locking member infront elevation. Figs. 7, 8, and 8 show a spring-tongue pivoted to theshank of the hook. Figs. 9 and 9 show a form in which the locking memberembraces the hook-shank. Figs. 10 and 10 are sections showing thelocking member in front elevation. Figs. 11

and 11 show a hook formed of two similar parts and the locking memberpassing through oppositely-formed recesses in each part. Figs. 12 and 12are partial plan views showing the recesses. Figs. 13 and 13 show asimilar structure applied to a hook having a pivoted spring-held tongue.Figs. 14 and 14: are partial plan views to show the recesses. Figs. 15and 15 show the locking member secured to the hook-shank instead of tothe tongue, and Fig. 15 a section showing the locking member inelevation.

In the structure shown in Figs. 1 to 4; the locking member or barattached to the springtongue a of the carbine-hook?) and formed in onepiece therewith, extends substantially from the bill of the hook to itsshank and is provided with an arrow-head-shaped projection d, which inthe locking position engages with the shank of the hook that has aswaged portion or notches f on each side. On pressing inwardly thetongue a one inclined surface of the projection (Z slides past the shankof the hook, whereby the bar 0 will first be deflected sidewise of theshank, and the projection will'then engage with the notch f of.

the shank, so as to hold the closing piece or tongue at in the openposition for enabling the loop or eye of the head oristud to be slippedon the hook, as shown in Figs. 3 and 4. 'On pressing with the fingerupon the projection cl in the direction away from the shank of the hookit will be disengaged, and the tongue a will then spring back into theclosed position.

Figs. 5, 5, 6, and 6 show a similar form of the projection cl on the bar0 of the spring-tongue a; but in this case the shank of the hook has awedge-shaped projection or swaged portion g, directed toward theprojection cl, and which on pressing the closing piece inwardly causesthe bar 0 to be deflected laterally and slide off one or the otherincline of the wedge y until the projection (Z springs into engagementwith the under side of the shank.

Figs. 7, 7, 8, and 8 show a construction similar to that last describedapplied to that kind of carbine-hooks in which the closing piece ortongue is not made in one piece with but is pivoted to the shank of thehook or to the stud or other attachment thereon and is held in closedposition by a spring or other known device. In this construction insteadof forming a wedge-shaped projection g, as in Figs. 5 and 6, projectingabove the shank of the hook this has wedge-shaped inclines it formedupon it that operate in the same manner as the projection g.

The locking-bar can also be made bifurcated or of a fork shape, as shownat Figs. 9, 9*, 10, and 10, the two arms 0' of the fork havingprojections on the inner side, which on pressing the closing-pieceinwardly engage with a prismatically-formed part A of the shank of thehook, so as to hold the closing piece or tongue both in the open andclosed position. One of these arms, 0, is somewhat shorter than theother, a, and both have notches that engage and spring over the edges[L2 of the prismatic part it of the shank, and thereby hold the tongueaway from the hook. A slight pull will by reason of the cooperatinginclined surfaces release the tongue. The longer arm 0 has a secondnotch 0, which when the tongue is in position to close the hook engagesthe prismatic portion A of the shank to lock the tongue in closedposition.

In the construction shown at Figs. 11, 11, 12, and 12 and also at Figs.13, 13, 14, and 14 the carbine-hook is split longitudinally or formed oftwo parts 2', fitting close together with spring action, through alooped part of which the locking-bar 0 passes. If this bar is subject tospring action, as at Figs. 11 and 12, it can be held in the depressedposition of the closingpiece by forming the loop 71: of the hookshankwith a central contraction, as shown at Fig. 12, so that on pressing thepiece a inwardly the bar 0 will be made to pass from the one end of theloop past thecontraction into the other end part, so as to be heldthereby, or if the bar has no spring action, as at Figs. 13 and 14:, itcan be formed with notches, such as those at Figs. 1 to 8, behind itsprojection (Z, with which notches the two parts of the shank engage withspring action, so as to hold the part a both in the open and in theclosed position.

Figs. 15, 15, and 15" show a construction in which the bar 0 is formedin one with or fixed to the shank of the hook, while the closing pieceor tongue (0 is split and formed with a loop in in a similar manner tothe shank of the hook in Figs. 12 and 13, through which loop the bar 0passes when a is pressed inwardly and is gripped by the spring action ofthe latter, so as to cause this to be held open.

Having thus described my said invention, what I claim as new therein,and desire to secure by Letters Patent, is
